FROM WIKIPEDIA
The Browning automatic rifle (BAR) is a family of American automatic rifle used by the United States and numerous other countries during the 20th century. The primary variant of the BAR series was the M1918, chambered for the .30-06 Springfield rifle cartridge and designed by John Browning in 1917 for the American Expeditionary Forces in Europe as a replacement for the French-made Chauchat and M1909 Benét–Mercié machine guns that U.S. forces had previously been issued.
